4WEB Medical Demonstrates Increased Subsidence Resistance for Lateral Spine Truss System Compared to Annular Implants

Via Markets Insider | October 26, 2017

4WEB Medical, the industry leader in 3D printed implant technology, announced the results of a new study demonstrating reduced subsidence for its Lateral Spine Truss System (LSTS) as compared to annular interbody implant designs today at the annual meeting of the North American Spine Society. The study was led by Vijay Goel, PhD at the University of Toledo, one of the country’s foremost orthopedic biomechanics institutes.

“Our biomechanical testing showed the 4WEB 18mm wide, 40mm long LSTS implant performed better in resisting subsidence than the competitive 21mm wide, 60mm long annular design lateral device. This finding was consistent across all density foam blocks tested. These results are indicative of the optimized load distribution that is inherent to the 4WEB truss implant technology,” said Vijay Goel, PhD at the University of Toledo.

4WEB’s proprietary open architecture truss design increases endplate to implant contact maximizing resistance to subsidence. The additive manufacturing process for truss technology provides a hierarchal surface roughness spanning from the nano to macro scale which may contribute to stimulating an osteogenic response… Continue reading.
